How do I install or upgrade an RPM package?
In order to install an RPM package you must first have the RPM you are trying to install on your system. Many people will download RPMs from a website and of course, Red Hat Network (RHN) provides all the RPM packages included in the distributions. There are two main flags that are used to install or upgrade RPM packages:
-i is used to install a new package. Always use this for kernel installations and upgrades.
-U is used to upgrade an RPM package but will also install a package if it does not exist in the RPM database.
Usage and additional options can be found in the RPM man page. Type man rpm from the command line.
Here is some information about the -i and -U flags:
INSTALL AND UPGRADE OPTIONS
The general form of an rpm install command is
rpm {-i|–install} [install-options] PACKAGE_FILE …
This installs a new package.
The general form of an rpm upgrade command is
rpm {-U|–upgrade} [install-options] PACKAGE_FILE …
Requirements for upgrading Ensim Control Panel
File system EXT3
Important: Quotas may not function as intended if you use other file systems.
Disk space At least 40 GB
Disk space partitioning:
/ 5 GB or more
(assuming minimum disk space of 40 GB)
/usr 5 GB or more
/swap Twice the size of RAM
The size of the partitions can vary in proportion to the size of the disk space.
/var 4 GB or more
/home 20 GB or more (depending on the number of sites you want to host)
Important: Do not create /home/virtual on a separate partition. The Site Administrator dashboard reports incorrect disk usage if the directory is created on a separate partition.
Troubleshooting Ensim Upgrade or Installer Issues
Problem : The host name of the server is incorrect.
Refer the log file /var/log/ensim/installer..-.log to review the list of successful and unsuccessful events recorded during the upgrade.
Check the file /etc/sysconfig/network. The host name must be a fully qualified domain name. See the following example.
Correct: myhost.mydomain.com
The file /etc/hosts should contain the host name and IP address of your server. If it does not, use an editor to modify the file.
—/etc/hosts begin file–
127.0.0.1 localhost.localdomain localhost
1.2.3.4 myhost.mydomain.com myhost
—/etc/hosts end file–
